Figure 1

Immunohistochemical staining of FOXP3+ T regs B7-H1 +and PD-1+ in T lymphocytes of breast tissues. Representative micrographs at × 530 magnification of (A&D) CD3/FOXP3 double staining (red color, membranous for CD3 and brown nuclear color for FOXP3 expression). (B&E) B7-H1 single staining (brown color, membranous/cytoplasmic expression). (C&F) PD-1 single staining (brown color, membranous expression). Upper panel (A-C) is sections for normal breast duct and lower panel (D-F) is sections for infiltrating ductal carcinoma of the breast.
